It can run normally and take effect, and finally delete itself. It's just that it prompts "Batch file not found" at the end. I've changed it countless times and really don't know what's wrong. Please help me take a look.

Remove @echo off and del %0, then check it yourself.

Mistakenly ^_^

I can delete here, but I can't run the batch file in this directory in the command line, prompting "Batch file not found"

Try:
del %0>nul 2>nul

It doesn't work. After adding AH, it still prompts that it can't be found.

Is it because there are long directories, directories with spaces, or Chinese directories?

Everyone can save my batch file and try it. No matter how I write it, it will prompt that the batch file is not found.

Error message:

WINDOWS cannot find the folder /IDLIST:252:856. Please confirm whether the file name is correct and try again. To search for the file, click the "Start" menu button and then click "Search"

I can delete here, but I can't run the batch file in this directory from the command line, and it prompts "Batch file not found"

Try:
del %0>nul 2>nul

I've already added it, but there are still error messages

It runs normally here, and after running, it can exit by itself and delete itself.

I can too, but if you look closely, there will be a last sentence, a prompt that the batch file is not found. Although it doesn't affect the use, I want to find out the reason.

First, do an experiment. Write a batch script with the content:
@echo off pause echo a pause

After running, don't press any key immediately. Right-click on that batch script and select "Edit". Change "echo a" to "echo b", save it, then switch back to the running batch window and press any key. The result is that "b" is echoed instead of "a"!

Do another experiment. The batch script content is as follows:
@echo off pause echo a pause

Similarly, after running, don't press any key. Then delete or rename that batch file. Then switch back to the batch running window and press any key. The batch directly exits without executing the following statements, and a line of error message is vaguely seen;

Regarding this, the following is a personal guess:

When a batch script runs, it doesn't load all the code into memory at the beginning. Instead, it loads the next line of code only after executing the current line. So we have the situation in the experiment where modifying the code midway results in executing the modified code;

Specifically for the original poster's batch script, because the batch script deletes itself during execution. After executing the "del" command, when the system tries to read the next line of commands downward, it finds that the batch file is not found, so an error occurs.

Use cmd /k to call that test batch file, and the results are easier to observe

```
@echo off
echo hello
del %0
```

```
@echo off
echo hello
del "%0"
```

```
@echo off
echo hello
del %0>nul 2>nul
```
Some people online say that you can't add a carriage return after del %0, but after my testing, no matter how I change the above three segments of code, it will report an error, the same as the building owner.
My test environment is XP SP2
Waiting for experts to appear

Agree with the statement of floor 12. I also tested it and got the same result as floor 14.
